Simple Voron V0 lights

This is a really simple LED holder for any Voron V0 that was inspired by the LED holders on the Voron Switchwire. 

There are 2 stls one for the left side and one for the right side. Just use VHB tape and put them under the Y 15x15 profiles. 

I use 24V LEDs that are connect to a relay and take power directly from the main power supply.

Here is a quick explanation on how I have configured mine:

• Add a relay and connect it to the raspberry pi on GPIO pin4 for signal and GPIO pin5 for ground. 
• Add the raspberry pi as an MCU to your klipper instance. Here is an explanation on how to do that: https://www.klipper3d.org/RPi_microcontroller.html
• Update your printer config with the following, in order to be able to control the relay from klipper:

[output_pin caselights]
pin: rpi:gpio4
value: 1

• Add several macros in order to be able to control the lights

[gcode_macro CASE_LIGHTS_ON]
gcode:
    SET_PIN pin=caselights value=1
[gcode_macro CASE_LIGHTS_OFF]
gcode:
    SET_PIN pin=caselights value=0

• Optionally if you want to automatically for the lights to turn on / off you can add the following to macro:

[delayed_gcode TURN_OFF_CASE_LIGHTS]
initial_duration: 300
gcode:
  {% if printer.idle_timeout.state == "Idle" %}
    CASE_LIGHTS_OFF
  {% endif %}

• Add the following to your print_start macro:

CASE_LIGHTS_ON

• Update the idle_timeout config with the following, in order to turn the lights off when the printer becomes idle:

[idle_timeout]
timeout: 900
gcode:
   TURN_OFF_HEATERS
   M84
   CASE_LIGHTS_OFF
